My wife was talking on the phone with her sister, who has a dog (but no children). During the phone call the dog mis-behaved and my sister-in-law ordered, "Bad dog. Get in your crate!"
My wife laughed at this and when she told me about it I mused about getting a crate for our children when they misbehave (which is frequent). Child abuse issues aside, my wife doesn't think it would work. We'd order one of our children into the crate and the other child would start screaming, "No, that's my crate. It's not fair she/he always gets to go in the crate and I never do."
